Just a reminder, you backtrace does not contain debug symbols, and you opened an upstream bug without the basic information:
1) Instruction to reproduce 2) System architecture (32bit/64bit if Intel) 3) Dependency version, especially GLib in this case
Note that I'm trying to be kind now, but we usually don't like to go back and forth from freedesktop bugzilla to launchpad bug system.
